Application of energy-filtering TEM to the nanocrystallization process in amorphous Fe84Nb7B9 alloy

The nanocrystallization process in amorphous Fe84Nb7B9 alloy was studied by means of energy-filtering transmission electron microscopy. Energy-filtered diffraction intensity provided quantitative structural analysis for the as-quenched state with the help of reverse Monte Carlo simulation. Using the Fe L-edge it was found from chemical mapping that chemical segregation of Fe with Fe-rich and Fe-poor regions starts to occur at the later stage of nanocrystallization.
